2 Claims. (Cl. 13250) The present invention relates to a novelly constructed and appreciably improved bobby pin of a dual or duplex type which is new in that it provides a two-way clamping action for end curls.

As the general statement of the invention implies, an object of the present invention is to structurally, functionally and otherwise improve upon the now well known bobby pin, this by providing a unique and improved adaptation which, in effect, accomplishes eifectual and reliable curl clamping results which could only be obtained by using two separate bobby pins for each curl.

The conventional bobby pin is characterized by two resilient legs or limbs which are in opposed general parallelism, are connected with each other at corresponding ends by way of a bend, one limb being flat and straight and the other limb corrugated or kinked. Despite the fact that the limbs clampingly grip the strands of hair, many users complain that a regular bobby pin does not hold satisfactorily. It is therefore common practice to apply one bobby pin to the curl and, in additiomto attach and thus apply a second bobby pin with the limbs of the latter straddling the limbs of the first named pin, and with the two pins at an angle, some times at right angles, to each other.

In carrying out the principles of the instant invention, a two-in-one or dual bobby pin is provided wherein two pins or units are integrated, that is, the two corrugated or crimped limbs are centrally interconnected and the two straight limbs are likewise centrally interconnected, whereby the respective units have their respective end portions disposed in outwardly diverging relationship,

whereby a generally X-shaped two-way clasping bobby pin is had.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying sheet of illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the views:

Figure l is a perspective view of a dual-type bobby pin constructed in accordance with the principles of the 7 present invention;

Figure 2 is a top plan view of the same;

Figure 3 is an edge elevation, that is, a view observing Figure l in a direction from left to right; and

Figure 4 is an exaggerated cross-section on the line 44 of Figure 2, looking in the direction of the arrows.

Briefly summarized, and by way of introduction to the detailed description, it will be seen that the invention in an over-all sense involves two duplicate bobby pins connected together in desired angular relationship.

Referring now to the drawings with the aid of reference numerals and accompanying lead lines, one bobby pin or unit is denoted by the reference character A while the complemental bobby pin is denoted by the reference character B. The first pin or unit A is somewhat conventional in that it is of an appropriate grade of spring steel or equivalent metal and embodies a substantially flat-faced linearly straight bottom limb 6, a top limb 8,

I (in Figure 1 connected by a curvate bend? 10. The

free end" portion. of limb -8-' is corrugated or provided with crimps or kinks 12. The terminal is flared laterally and away from that of the first named limb, as at 14 and 16, respectively. The second bobby pin or unit B is a duplicate of the unit A, and it comprises a linearly straight bottom limb 18, an opposed top limb 20 with two having their left hand ends joined by a curvate bend 22 and having their free ends 24 and 26 spaced apart in the manner illustrated. The end portion 28 of the limb 18 underlies the corrugated or crimped end portion 30. The bottom limbs 6 and 18 are crossed intermediate their ends, as at 32, while the upper limbs 8 and 20 are likewise centrally crossed, as at 34. It is within the purview of the invention to actualy overlap and thus cross the respective intermediate limb portions or, as is shown in the drawing, to have them in coplanar relationship, under which circumstances, it may be said that they intersect each other. In any event, the respective limbs of the respective units are in crossed relationship so that the respective end portions are in divergent relationship. This means that looking at the over-all structure in side elevation, it is of X-shaped configuration, as perhaps best shown in Figure l and 2.

If desired, it is within the purview of the invention to provide rubber sleeves or protective tips 36 on the spreadable ends of the respective units. These tips are designed to afford protection to the scalpof the wearer.

It is submitted that the advantage of this well balanced and ornate appearing dual type bobby pin over the single bobby pin construction is that when the user makes a curl and secures it with this improved pin, it will not be necessary to use another or second independent bobby pin to hold the first bobby pin and curl in place. As before mentioned, many women, perhaps hair dressers, too, have found that when they put up hair with bobby pins, it is necessary for them to use at least two bobby pins for each curl in order to hold the curl in place, particularly if they are going to keep the pin cufls or end curls fastened over night. The two-way or dual clasp-type pin construction herein revealed does away with this and does a complete job of holding the curl since it is of one piece, and thus holds the curl securely from all sides. It is particularly advantageous when used in putting up the hair using either water or dry set, and, of course, it is satisfactory, too, in connection with socalled home permanent preparations because a reliable and secure gripping action is ensured.

Since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.

What is claimed as new is as follows:

1. A dual-type bobby pin comprising a first unit embodying opposed resilient clasping limbs connected with each other at one end of said unit and free of connection with eachother at the other end of said unit, and a second unit, said latter unit being a duplicate of the first unit also'having opposed resilient hair clasping limbs,

corresponding limbs of the respective units being integrally joined with each other, the limbs of said units being joined at their intermediate portions, and intersecting each other and the respectiveiend portions of the respective units being disposed in divergent relation,

4 tegrally joined and thus connected at the other end of in divergent relationship whereby the over-all bobby pin the unit, each limb of each unit being connected to a 18 P in P correspondrng limb of the other unit and a point on each References Cited in the file of this Patent limb which is intermediate the free end of each limb and its connection to the other limb at the other end UNITED STATES PATENTS of the unit, the respective end portions of the respective 1,893,514 Burch Jan. 10, 1933 units being disposed in coplanar reationship and also 2,136,883 La Pour NOV. 15, 1938
